Katy Perry just dropped her new music video for 'Teenage Dream' yesterday. And when we watched it, we immediately wanted the low-rise, ripped denim jeans she wears while partying on the beach! (Also, don't you just love how she styled them with combat boots — perfect!) She even gave her pants a special shout-out in the song: "I might get your heart racing / In my skin-tight jeans / Be your teenage dream tonight." Turns out, they're Diesel's Livier 65Z jeans, and you can snap them up for $170 online starting November 15. We know — it's SO. FAR. AWAY. But at least we can play Katy's video on repeat while we suffer through the wait.
